ELECTRIC HEAT
If the unit is to be equipped with an electric heating kit, the latter must be installed on the blown air duct inside
the building.
Safety devices (automatic and manual reset thermostats) protect the appliance against any possible risks of
overheating due to insufficient flow around the shielded elements.
The electric heating kit power supply must be separated from the
HAN
unit's power supply. Only the electric heating
control functions are managed by the
HAN
unit (refer to appended wiring diagrams).
AIR FLOW / pRESSION ADJUSTMENT
SEE TO AppENDED AERAULIC CHARACTERISTICS
The
HAN
models 10 and 13 are equipped with direct drive centrifugal compressors.
From
HAN
model 15 upwards, air flow / static pressure is adjusted via a variable pulley. When adjusting this pulley
it is important to ensure that the drive belt is positioned correctly. The latter must not move out of its groove or be
located at the bottom of the groove. The pulley/drive belt assembly must be perfectly aligned and the belt must be
properly tightened in accordance with specifications.

For a quick check, make sure that the small
rope touch each end of the pulleys as shown
on drawing above.

The
HAN
roof-mounted units are designed for ducted applications. In the event of an application
without a duct network on the blowing side ("free" blowing) it is necessary to create an artificial pressure
loss on the blowing side to avoid damage to the fan motor due to an abnormally high current draw.
This pressure loss can be created for example by adding a perforated plate that will also have the
effect of improving blown air distribution.
To achieve optimal performance, this plate should be of an adequate size and suitably positioned to ensure that
the airflow is close to the unit's nominal airflow.
